感受態(tài)細胞的制備是基因重組中一項基本技術(shù)，是獲得高質(zhì)量基因文 庫的關(guān)鍵。由于誘導(dǎo)細菌進入感受態(tài)的機制尚不完全清楚，且感受態(tài)細胞的轉(zhuǎn) 化率受諸多因素的影響，實驗室之間差異較大。尤其在室溫較高時，感受態(tài)制 備的效果很不穩(wěn)定，摸索高溫季節(jié)制備高效感受態(tài)細胞的方法仍十分必要。此 外，高效感受態(tài)細胞貯存不當會很快喪失其感受性，如何較好地貯存感受態(tài)細 胞亦是一個亟待解決的問題。制備感受態(tài)細胞的方法很多，而CaCl2法是目前 實驗室制備感受態(tài)細胞較為常用的方法之一。
